British Antarctic Survey

Scientists studying huddles of emperor penguins in Antarctica have discovered that waves of movement travel though huddled masses of flightless birds - but in ways that maximize the huddle's density and keep the birds warm.

Young salmon with no migratory experience somehow voyage through vast, shifting ocean waters to wind up at specific feeding grounds that are hundreds of miles away from the rivers where they were hatched. Scientists think they use a "magnetic map" and a sort of "mental GPS."
